The 21-year-old made his international debut in the 52-21 victory at the Aviva Stadium last night, and thought he'd scored a try until referee Marius van der Westhuizen deemed Paddy Jackson's pass in the build-up to be forward.

“It was too good to be true...it was a great ball by Paddy, but the referee called it back,” he told RTÉ Sport.

“I can’t complain, I’m over the moon to get a win like that, to get through it safely. I’m delighted with the result.”

Ireland made 15 changes from the team which beat the All Blacks last week, and Ringrose was one of eight previously uncapped players to make his Irish debut.

The Leinster centre also revealed that international rugby is a "real step-up" from provincial rugby.

“I had been in a couple of camps, but this is the first overall 32-man squad I have been named in.

“To be over in Chicago and getting experience of what is expected of the players, it is a real step-up.”
